Hello,using LO 3.4.1 (Win7) here I see that table cell borders are not printed while preview looks okay?!The borders are only printed correctly when the table is empty - as soon it contains text/images cell borders are blank.

This is the same when printing into a pdf or on paper suggesting it's not a driver problem.

I can confirm this. Printing problems in LibreOffice 3.4.0 have been reported as one of the most annoying bugs. Unfortunatelly the situation hs not improved much in LibreOffice 3.4.1.

It seems that cell borders do not work together with graphics so if you have to use cell borders ant graphics at the same time the only workoround is to export the document to PDF and then print it. Be aware - use the in-built export feature and do not export the file to the PDF under virtual printer.
